LG UltraGear LG UltraGear 31.5" Dual Mode 4K UHD 240 Hz / FHD Review
The LG UltraGear 32GX870A-B promises 4K OLED glory at 240Hz, but our data reveals a product plagued by quality control failures. Find out why we can't recommend it.
The 30-Second Version
Spectacular specs, shameful quality control. This monitor is a beautiful-looking gamble, and the house usually wins. Until LG fixes its panel lottery, buy something else.
Overview
The LG UltraGear 32GX870A-B is a monitor that promises everything: a 4K OLED panel, a blistering 240Hz refresh rate, and a wild dual-mode feature that cranks out 480Hz at 1080p. On paper, it's a dream machine for anyone who wants the best of both worlds—stunning visuals and competitive speed. But here's the one thing you need to know: our data shows a massive disconnect between its incredible specs and the real-world experience buyers are having. The panel quality control seems to be a genuine gamble right out of the box.
Performance
The performance story is a tale of two monitors. When it works, it's phenomenal. That OLED panel hits the 100th percentile for color in our database, and the 240Hz refresh at 4K is buttery smooth. The dual-mode trick to hit 480Hz at 1080p is a neat party trick for esports purists. But the 'when it works' is doing a lot of heavy lifting. The 83rd percentile performance ranking feels generous when you consider the number of units arriving with serious visual defects that ruin the experience before you even start a game.
Pros & Cons
Pros
- OLED picture quality is absolutely top-tier when it's good. 100th

- A shockingly low 2.5/5 customer rating for a premium product.
- It's a pricey gamble—you might get a perfect panel or a defective one.
- The social proof score is in the 5th percentile, meaning very few people are vouching for it.

Value & Pricing
At a price spread of $952 to $1397, the value proposition is broken. Even at the low end, you're spending nearly a grand on a product with a documented history of defective arrivals. No amount of specs can justify that kind of risk. Until LG addresses these QC problems, it's impossible to call this a good value. If you find it for $952, you're still rolling the dice.
Price History
vs Competition
This puts it in a tough spot against its competitors. The ASUS ROG Swift 32" 4K QD-OLED offers a similar stunning OLED experience at 240Hz but with a much stronger reputation for reliability. The MSI MPG 32" 4K 240Hz is another direct rival, often at a similar price point, but without the OLED panel. If you want sheer size and immersion, the Samsung Odyssey Neo G9 is a different beast entirely. For our money, the ASUS is the safer bet for the same core experience, and the MSI is a more reliable alternative if OLED isn't a must-have.

Common Questions
Q: Is the 480Hz mode at 1080p worth it?
It's a cool trick for hyper-competitive esports players, but for most people gaming at 4K, you'll live at 240Hz. Don't buy this monitor just for that feature.
Q: Should I be worried about OLED burn-in?
Modern OLEDs have mitigations, but it's always a long-term consideration with static elements. For mixed use, it's a minor worry. For a dedicated gaming monitor you'll cycle content on, it's less of an issue.
Q: Is the USB-C port good for laptops?
Yes, the 90W USB-C is perfect for a single-cable connection to power and run a high-end laptop, which is a great feature for a clean desk setup.
Who Should Skip This
If you're looking for a reliable, premium monitor that just works out of the box, this isn't it. Go get the ASUS ROG Swift 32" QD-OLED instead for a similar (and more trustworthy) OLED experience. If you're on a tighter budget and want high refresh 4K, the MSI MPG 32" is a solid non-OLED alternative.
Verdict
We cannot recommend buying the LG UltraGear 32GX870A-B in its current state. The specs are a siren song, but the reality, backed by a flood of negative user experiences, is a product lottery you don't want to play. For a monitor in this premium price bracket, reliability is non-negotiable. Until LG publicly acknowledges and fixes these widespread panel issues, your money is better spent on a competitor that can deliver on its promises consistently.
